Sun, Jxta And Promises
A reader writes: "There's a publically available article on the WSJ online regarding Sun and the Jxtra launch. But the interesting part is the spin on Jxta as Jini, essentially repackaged. The article also gets into Jxta trying to ride on the coattails of the 'p2p' success. Good article."
Sun seems to have forgotten the reason why Java took off. Java was doing something amazing in 1995. There was a tiny program running in a browser, and the same program running on both Windows and Solaris. This was something new. Of course, applets haven't worked so well in non-trivial cases, but it got interest going in Java.
Compare this to Jxta. What does Jxta let me do that nothing else can do? Writing a P2P app isn't rocket science; a freshman CS major can probably do a decent job of it. Maybe if Sun had released the Jxta killer app along with Jxta, it might be more interesting. For now, though, it looks like it's probably going to fizzle out.

No, as I recall, the license fees for Jini only kicked in when you started selling devices with Jini on them, and then it was only to the tune of $0.10 per device, or a one-time fee of $100,000 or $200,000 for those who would be selling millions of devices. These fees have recently been removed completely.
I don't know about an open source version of Jini, but I do know that there is a vendor that has built an independant version of Jini (http://www.prosyst.com), and another company that built an independant Jini Look-up server. Sun didn't squash those efforts.
I agree with Bill Venners, who was quoted in the article. Sun marketed Jini as an infrastructure that would tie together all sorts of devices. The trouble was, it is still the case that you need a lot of RAM and ROM on a node to host Jini, unless you use some sort of surrogate architecture. With arrival of the Connected Device Configuration (CDC) and the expected arrival of the RMI profile, you soon will be able to host Jini on smaller devices but it still will take 2-3 meg. of memory.
I also think that it is premature to dismiss Jini as a failure. I am seeing more and more products in the pipeline that are using Jini, and it is also seeing more use in enterprise-type applications. Did it take over the world? No. Is it being abandoned by early adopters? Again I think, no.
I think that the above post is yet another reason to not rely on a Slashdot posting for your information. There may be some gems, but the above posting has a pretty low accuracy level.
1997 - Personalization
1998 - Push
1999 - Streaming Media
2000 - WAP
2001 - P2P
Next year it will be the "X Internet". You can safely avoid all of these fads and still enjoy a healthy networked computing experience.
My company is involved in the JXTA innitiative, and while JXTA is not much to holler about yet, it is on its way. To have a set of protocols that allow not only groups of peers on a network to communicate, but other networks outside that group to interact, is a HUGE step for not only Peer-to-Peer technology, but for networking as a whole. While the jury is still out on the success of JXTA, it is projects like this that will shape the future of networking as a whole.
Personally, I like it. But it will be up to the JXTA community to make it a reality. So far, their is progress, but still a ton of work to do.
